Microalgae for use in tropical aquaculture I: Gross chemical and fatty acid composition of twelve species of microalgae from the Northern Territory, Australia

Biosorption of phenanthrene by pure algae and field-collected planktons and their fractions

“…Lipids show the bands at 2800 and 2950 cm À1 for aliphatic chains (Blokker et al, 1998;Rodríguez and Cerezo, 1996;Mecozzi et al, 2011). In the previous investigation, it was found that the major components of algae are lipids, proteins, carbohydrates together with smaller amount of resistant polymers (such as algaenan) (Renaud et al, 1994;McDermid and Stuercke, 2003). Hence, the investigated samples are confirmed to be the combination of several biomolecules (proteins, carbohydrates, lipids, and algaenan).…”

Chemical composition and release rate of waste discharge from an Atlantic salmon farm with an evaluation of IMTA feasibility

“…The N:C (62-99 µg N mg −1 C) and N:P (0.8-1.8 mg N mg −1 P) ratios of salmon faeces were lower than those of some phytoplankton species, whereas the P:C ratios of salmon faeces were far higher than that of some phytoplankton (Table 5). The lipid content of salmon faeces (64-89 mg g −1 dry weight) was in the range of that of some marine diatoms (24-278 mg g −1 dry weight) (Renaud et al 1994, Liang et al 2000, which dominate the spring bloom in the Trondheimfjord (Sakshaug & Myklestad 1973). Moreover, the DHA and EPA contents of salmon faeces were similar to the levels of diatoms and Prymnesiophyceae (Isochrysis galbana), respectively (Reitan et al 1994, Renaud et al 1994, Liang et al 2000.…”

Our results indicated that salmon faeces have a poorer nutritional value than salmon feed and some microalgae, but that this particular food source still can be adequate to support the growth of bi valves in an IMTA system.…”

Microalgae and Wastewater Treatment

“…Currently significant interest is developed in some advanced world nations such as Australia, USA, Thailand, Taiwan and Mexico (Borowitzka andBorowitzka, 1988, 1989a,b;Moreno et al, 1990;Wong and Chan, 1990;Renaud et al, 1994). These are due to the understanding of the biologists in these nations for the biology and ecology of largescale algal cultures, as well as in the engineering of large-scale culture systems and algal harvesting methods, all of which are important to the design and operation of high rate algal cultures to produce high-value products, such as Pharmaceuticals and genetically engineered products (Javanmardian and Palsson, 1991).…”
